sonnes.;

My invention relates to a .safetyl razor and has for its principalobject, to provide a simple practical and inexpensive structure,including a handle, blade holder and blade wherein the holder andbladeare constructed and shaped so that the holder will receive and clamp,only those blades which are specifically produced and shaped for use invsala'zl holder, thereby overcoming the indiscriminate use of variousshaped blades with the holder.

There are at present, on the market, a number of safety razor bladeholders which will receive and clamp, many dilerent makes of razorblades, some of which may of inferior quality andy for the protection ofmanufacturers of high grade safetyl razors and blades, I propose toprovide a holder which will receive only those blades which are producedfor complementary use in such holder.

With the foregoing and other objects in view, my invention consists lincertain new and novel features of construction and arrangement of partswhich will be hereinafter more fully described and claimed andillustrated in the accompanying drawing in which Fig. 1 is'a top planview of one form of my improved razor made Fig. 2 is a. verticallongitudinal section taken through the center of the holder.

Fig. 3 is a perspective view'of the two blade blade used with the formof holders shown in\ Fig. 4. v

Fig. 6 is a perspective view of a rfurther modined form of blade.

' Referring by numerals to the accompanying -drawing and particularly tothe 'construction illustrated'in Figs. 1, 2 and 3, l0 designates thelower member' 'of the holder, which is curved transversely and providedon' its longitudinal edges with conventional safety razor teeth Il andformed'in the center of this member l0 is an grooved members.

c1. sc-vol p ber and enters a threaded bore Il, in the upsharplongitudinal edges and formed inthe center of saidblade is anl aperture2| for'the reception of stud i6 when the blade is positioned in theholder.

lFormed in the blade in longitudinal alignment with each other and withaperture 2l, are

indentations which provide small studs 22, located and spaced so as toenter the recesses i3 and I8 when the razor partsare assembled.

Obviously the num-ber of the recesses I8, and Il, and studs 22 may vary,although as illustrated, I prefer to provide for each of said recessesand studs, two on each side of the stud IB and aperture 2| andwith themembers of each pair of studs 22-reversely arranged, l. e..

one stud projecting from one face of the -blade* and lthe otherprojecting from the other face.

Thus, when a blade is positioned in the holder,

two of the kstuds 22 are seated in two of the recess'es l2 in lowermember Ill with th'e other `two studs seated in two of the recesses I8in upper' member' I4 and when the handle I1 is screwedv onto stud I5,the blade will be clamped between plates vIII and".

Inasmuch as the blade .engaging faces of the frame member lll and 'Ilare devoid of all ribs.

stud grooves and the like, it, will be impossiblel to yapply and clampbetween said members, blades which are especially constructed forcooperative use with such ribbed, studded or In Figs. 4 and 5, 'I' have.shown afmodiiled structure wherein the inner faces of the -frame platesare provided with ,registering'recesses 2l adapted t0 receive the headsof studs or rivets Formed in the upper surfaceof member IU inlongitudinal alignment with aperture I2 are ,small shallow recesses Il.e l

The upper member Il of V`the holder is ores cent shape in cross sectionequal in length, but

slightly shorter thanlower member I ll and depending froni the undersideof said upper member is a centrally arranged'threadedl st ud whichpasses through aperture I2 in the vlower mem- "28, on both faces of theinterposed blade.

'In ne. 6,- the blade 1s shown indented so asftn form two studs 21, withone projecting from each face 'of said blade. I'his form of blade maybey used with the form of -holder seen in Fig. 4.

It is to be noted that in my improved razor blade there isat least' onestud such as 22, 26

or 21 projectingoutwardly from each face of the blade and1thus thelatter cannot lie flat -after use.

Thus it will be seenAthat I have provided a safety razor wherein theholder and blade are constructed so that said holder will receive andclamp, only those blades intended to be used with the particular holder,thus preventing the indiscriminate use of blades with the speciallyformed holder.

My improved safety razor is simple in struc# ture, inexpensive ofmanufacture and very effective in performing the functions for which itis intended.

It will be understood that minor changes in the size, form andconstruction of the various parts of my improved safety razor may bemade and substituted for those herein shown and described withoutdeparting from the spirit of my invention, the scope of which is setforth in the appended claims.

, I claim as my invention:

1. In a. safety razor. a holder comprising a p air of plates, a bladeadapted to be positioned between said plates and pairs of interengazlnsst uds and recesses on the contacting faces of said plates and bladebetween the centers and ends thereof.

l 2. A safety razor as set forth in claim 1 and means including a handlefor clamping said plates and blades to each other.

3. In a safetyv razor, a holder comprising a pair of Aplates provided ontheir adjacent faces with pairs of recesses disposed between the centersof said plates and the ends thereof, a blade adapted to be positionedbetween said plates and pairs of studs on said blade between the centerand'ends thereof for engagement in the recesses in said plates.

4. A safety razor as set forth in claim 3 and with means including ahandle for clamping nsaid plates and blades together.
